Incorrect GUI client size

[FredAI]

The script below worked fine in the version 3.3.8.1.
When using the version 3.3.10.2 or the latest beta 3.3.11.5, WinGetClientSize() and the GetClientRect() Windows api do not exclude the area occupied by the menu like they should.

#include <WindowsConstants.au3>
_main()
Func _main()
	$Gui = GUICreate('Menu and edit example',400,300, -1,-1, _
	BitOR($WS_MAXIMIZEBOX,$WS_SIZEBOX,$WS_CAPTION,$WS_SYSMENU,$WS_MINIMIZEBOX), $WS_EX_ACCEPTFILES)
	$menu = GUICtrlCreateMenu('File')
	$apos = WinGetClientSize($Gui)
	$edit = GUICtrlCreateEdit('',0,0,$apos[0], $apos[1])

	GUISetState()
	While GUIGetMsg() <> -3

	WEnd
EndFunc

What exactly are you demonstrating with the script posted? Where are you showing that WinGetClientSize isn't returning the correct size?

When I run that script I get the following in the Au3Info tool.

I'm not saying you're wrong, I'm just not sure what you're expecting to see and what you're actually getting.

Just run that script with both versions 3.3.8.1 and 3.3.10.2 and you'll see what I mean.

I use WinGetClientHeight() to get the size of the client area after adding the menu. That allows me to create an edit control of the same size as the remaining client area, just like the notepad window. In the version 3.3.10.2, the edit control is too tall, and the bottom scroll bar gets hidden. It works fine in the version 3.3.8.1.

The info you got with the Au3Info tool demonstrates exactly what I mean. Initially, the window is created with 400x300 px. After adding the menu, the client hight should be 300 less that menu's height, which would make ~280 px.

That's the expected behavior. Try creating a GUI with a menu in C. You'll see.

See #2588 and use GUICtrlCreateMenu() after GUISetState()

Replying to anonymous:

Thanks. I like to create all the controls while thw GUI is hidden, so I found a better solution. We just have to call GUISetState(@SW_ENABLE)immediatelly after creating the GUI.

Then we can create all controls before calling GuiSetState(). Hope it helps to fix the bug.

Checking with 3.3.14.4 and it works so we fix it without closing
